MACHINE-SEWED BOOT OR SHOE.

SPECIFICATION forming part of Letters Patent No. 319,269, dated June 2, 1885.

Application filed March 523, 1885.

` To @ZZ whom t may concern,.-

Be it known that I, WILLIAM A. KNEE, of Haverhill, in the county of Essex and State of Massachusetts, have invented certain Improvenients in Machine-Sewed Boots and Shoes, of which the following is a specification.

This invention relates to boots or shoes in which the outer soles are stitched to the uppers and inner soles by machine-made stitches laid in a channel formed by cutting into the outer surface of the outer sole, as by the McKay stitching-machine. A iiap is formed on the outer sole in cutting the channel, and after the stitching operation said iiap is cemented to cover the channel. The outer edge of the ap is thin, and is liable to become detached from the body of the sole by wear, and thus give the sole an unsightly appearance when the outer edge of the ap is iiush with the outer edge of the sole.

My invention has for its object to protect the outer edge of the channel-flap, and at the same time give a thin and neat edge to the outer sole without detracting from the thickness of the sole at the point where the stitches pass through it.

To this end the invention consists in a machinesewed boot or shoe having its outer surface cut away near its edge, so that the outer edge of the iiap will not be iiush with the bottom or wear-sustaining portion of the sole, as I will now proceed to describe.

Of the accompanying drawings, forming a part of this specification, Figure l represents a transverse section of a machine-sewed boot or shoe having my improvement. Fig. 2 represents a similar section before the sole is cut away on its outer surface.

The same letters of referenceindicate the same parts in all the figures.

(No model.)

In the drawings, a represents the outer sole, b the upper, and c the inner sole, the outer sole having the usual stitch-receiving channel, d, covered by the flap d.

In carrying out my invention I take a boot or shoe after the outer sole,a, hasbeensecured by the stitches s, and the iiap d has been cemented down, as shown in Fig. 2, and with a suitable trimming-tool remove a portion of the outer surface of the outer sole near the edge thereof, so as to reduce the thickness of the edge and form a surface, t t, above the wearing or outer surface of the sole on which the outer edge of the flap d'terminates. The outer edge of the flap is therefore raised above the wearing-surface of the outer sole when the sole is in use,and is thus protected from injury to a considerable extent, while the sole is reduced in thickness,and thus given a neat and light appearance at the edge without being reduced in thickness at the point where the stitches s pass through it.

The surface t t may be burnished or otherwise finished in any desired manner.

I claim- A machine-sewed boot or shoe, the sole of which is channeled on its outer or tread surface,and cut away near its edge, to form asurface, t t, on which the outer edge of the channel-nap terminates, said surface being above the tread-surface of the sole, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 17th day of March, 1885.

VILLIAM A. KNIFE.
